Title: Machine tool loading mechanism
IPC: B24B41/00
Filed: 1960-10-28
Abstract: 906,386. Centreless grinding. CINCINNATI MILLING MACHINE CO. Oct. 28, 1960 [April 1, 1960], No. 37088/60. Class 60. [Also in Group XXX] Workpieces are discharged from a magazine into a centreless grinding-machine by ram 70. If a blockage occurs in the feed from the magazine the ram 70 is caused to retract. This is achieved as follows. The ram is reciprocated by hydraulic motor 36 which actuates piston 54 secured to ram 70. Motor 36 is controlled by reversing valve 84, by on-off valve 82, and by pressure-reducing valve 85, which control the fluid supplied from source 90. Additionally there is auxiliary valve unit 40. Piston 54 and ram 70 are caused to move rightwards by pressure-fluid introduced at 41 and then caused to move leftwards by fluid-pressure introduced at 51, lines 21 and 31, respectively, returning the fluid to sump. Auxiliary valve unit 40 responds to any blockage or stoppage of the ram. The piston 54 is rigid with sleeve 60 on which a shoulder 77 is formed, and sleeve 60 is rigid with valve spool 66 of valve unit 40. The ram 70 is rigid with valve body 102 of the valve unit 40, and valve body 102 is urged against the shoulder 77 by fluid in chamber 102 supplied at 61. Normally, therefore, ram 70 and piston 54 reciprocate as a unit together, with the valve body and shoulder in engagement. Should, however, the resistance encountered by ram 70 exceed that corresponding to the fluid pressure in the chamber 102 the valve body 102 moves leftwards relative to valve spool 66 to permit lines 13 and 21 to be connected together by spool 66. This causes a pressure differential between ports 94 and 96 of reversing valve 84. This in turn causes reversal of said valve so that piston 54 is caused to move leftwards and to bring the ram 70 with it. Thus ram 70 is retracted prematurely. After this retraction, normal operation resumes. If the obstruction persists the ram 70 is again prematurely withdrawn and this continues until the obstruction ceases.

Abstract: 1313258 Electroluminescence LICENTIA PATENT-VERWALTUNGS GmbH 18 Aug 1971 [27 Aug 1970] 38718/71 Heading C4S [Also in Division H1] A semi-conductor laser, Fig. 4, comprises a central layer 4 which is a mixed crystal of two III-V compounds and two outer layers 2, 3 which are both binary III-V compounds. The two outer layers need not be the same material; one of the III-V compounds in the central layer is the same as one of the outer layers, while the other compound in the central layer is of a lesser band gap. This produces a refractive index difference between the central and outer regions which helps confine emission to the central portion. One of the outer regions is P-type, the other N-type, while the central region is weakly P-type, thereby forming a single PN junction. The outer regions, being binary III-V compounds, are good electrical and thermal conductors which reduce ohmic heating and aid heat-sinking so that continuous room temperature operation is possible. External electrodes can also be added to the binary III-V compounds with low ohmic losses. Suitable compounds are: for the outer layers, GaAs, InP, GaSb or InAs, and for the central region GaAs-InAs, GaAs-GaSb, GaSb-InSb, InP-InAs, InP-InSb or InAs-InSb. Telecommunication applications are exemplified.

A metal starter sleeve 50 with sealing rings 52 of graphite tape is fitted in the mould portion 28 before the mouthpiece 26 is press-fitted in and clamped, with the ring 24, by a bolted ring 58, before the mould assembly 22 is bolted to the vessel 10. After preheating the whole assembly, a starter bar 38 is inserted from the mould outlet end. It comprises a hollow shank 40 capped by an insert 42 and bears a chill ring 44 on a bolt 46 with A1 wire 48 on it for killing the first steel poured. A rod 56 screwed into the bolt 46 supports a fusible plug 54 for fitting into the vessel outlet 14 to delay entry of the poured steel into the mould 28, 30, to allow slag on the steel to rise above the outlet 14. The steel, before solidifying in the sleeve 50 and around the bolt 46, melts both the fusible plug 54 and its support rod 56. The bar 38 is then withdrawn a short distance by rollers, started by an operator or by an electronic control at a signal from a thermocouple 27 which will indicate a slight temperature difference between pull and dwell. After a dwell period (during which some reverse movement may be applied) to allow a segment of steel skin to form between the mouthpiece 26 and the starter sleeve 50, the pull and dwell cycle is continued to form fresh successive segments of skin. A water jacket 32 surrounding the mould 28, 30 contains a baffle 39.

Abstract: 1,010,609. Pulse circuits. RADIO CORPORATION OF AMERICA. Oct. 15, 1962. [Nov. 2, 1961], No. 39000/62. Heading H3P. A pulse generator comprises a plurality of gates each feeding an output line, a feedback path via a first delay device from all the output lines to the input of each gate for controlling pulse duration and a further feedback path via a second delay device from all output lines to the inputs of at least some of the gates for controlling the interpulse interval. Initially, all inputs to the NOR gate 126 are zero with the exception of the starting signal H. A pulse C1 is initiated by the NOR gate 126 when the starting signal becomes a binary 1. The onset of pulse C1 is passed via an OR gate 130 to set a bi-stable circuit 116, giving an output #F which is inverted at 134 and passed via a delay line 136 to an invertor 138 giving a waveform #P and via a further invertor 146 giving the inverse waveform P (Fig. 5). Pulse C1 is terminated by waveform P inhibiting the NOR gate 126. Waveform P is inverted at 140, delayed at 142, inverted at 144 and 68 and fed to an asynchronous adder 70, the output of which is inverted to provide waveform Q and its inverse Q. Waveform #Q enables the NOR gate 122 thus initiating a second pulse C2 which is terminated by waveform P after a delay due to the line 136. After a delay due to line 142, waveform R enables the NOR gate 128, initiating a pulse C3. Bi-stable circuits 110, 112, 114 are provided to control the NOR gates 118 . . . 128 so that only one pulse is present on any one line at a time. It will be noted that all pulses have a duration X due to the delay inserted at 136 but the interpulse interval is either Y or Y + Z. The NOR gates may be replaced by AND gates if appropriate changes in the polarity of the various waveforms are made. Figs. 2, 3 (not shown) relate to a similar arrangement but wherein the interpulse period is always controlled by the same delay line. After one pulse has been produced on each line, the system is reset by means not shown.
